Custom ADU Design and Construction in San Diego
SOHO Architecture & Construction offers ADU design and build services in San Diego, guiding clients through the entire process from initial concept to completed construction. Whether the goal is adding a backyard cottage, a guest suite, or a rental unit, their team handles permitting, design, and construction as a single integrated service.
An accessory dwelling unit (ADU) is a secondary housing unit located on a single residential lot. It can be attached to or detached from the primary residence, and includes its own kitchen, bathroom, and sleeping area. ADUs are known by several names, including granny flat, casita, guest house, in-law suite, companion unit, or mother-in-law apartment. They offer flexible housing options — whether for family members, long-term renters, or as an additional income source.
SOHO Architecture & Construction works with the following ADU types:
- Detached ADU — a standalone structure separate from the main home, often referred to as a backyard cottage or granny flat
- Attached ADU — an addition connected to the existing primary residence
- Conversion ADU — converting existing space such as a garage into a livable unit, also known as a garage conversion
- Junior ADU (JADU) — a smaller unit created within the existing footprint of the home
How SOHO Approaches Each Project
SOHO Architecture & Construction follows a structured process designed to keep clients informed and involved at each stage. The process begins with a consultation focused on understanding the client's goals, lifestyle, and vision. From there, the architecture team develops drawings, blueprints, and 3D renderings so clients can visualize the planned space before any construction begins.
Prior to breaking ground, all project details — including selections, schedules, and approvals — are organized through a dedicated project management board. This gives clients a clear picture of where things stand before work begins.
During construction, the team manages the full build from framing through to final finishes. Clients receive a custom Gantt chart updated weekly with progress, timelines, and milestones. Real-time communication threads with the architect and designer are also maintained throughout, keeping all parties aligned as the project moves forward.
Once construction is complete, SOHO provides a warranty plan — referred to as the SoHo Comfort Warranty Plan — covering the completed work beyond the move-in date.
Project Management and Communication
Transparent communication is a central part of how SOHO Architecture & Construction operates. They use an online project management platform to facilitate collaboration between clients, architects, and the construction team. This system is intended to reduce uncertainty and keep clients informed throughout the duration of their ADU project.
With combined experience across construction, architecture, and development, SOHO positions itself as both a builder and an advisor — helping clients navigate the often complex permitting and construction requirements associated with ADU projects in San Diego.
Their approach incorporates current building techniques and sustainable practices, with the aim of delivering results that meet present standards while remaining adaptable to future needs.
